I applied via my college recruitment and had an initial phone round. The question asked was average in difficulty, requiring good knowledge of recursion and hashing. I passed the phone round and was scheduled for an onsite interview in the same week.

I interviewed at Bloomberg's NY HQ and received my offer within a week of the onsite.

The interviewers were nice and helpful. The HR team was quick and organized in scheduling interviews and notifying results.

Bloomberg has a gorgeous office. The interviews are slightly difficult, but the interviewers are helpful and guide you if you're stuck, as long as you keep thinking out loud.

I interviewed on a Thursday and received my offer on the following Monday! I had a competing offer, and they matched it during salary negotiations. They also offer awesome perks and benefits.

My onsite interview consisted of a total of 4 rounds. Three of them were fully technical, and one was with HR. They expect you to answer on paper using a pen or pencil rather than whiteboarding.

Round 1: Two Senior Devs. I answered about 4 coding questions. They included sorting algorithms, hashing, and DP. I'd say they were medium-level questions on LeetCode.

Round 2: Two Senior Devs. I answered 2 questions. These were completely new questions; I had never encountered anything like them before. They required knowledge of mathematics (line equations, slopes, etc.), caching mechanisms, and distributed systems.

Round 3: HR. Very general questions.

Round 4: One Very Senior Dev. He asked a system design question: What components would you use to design systems, how to architect them, make them scalable, and justify all your design decisions.

They provide a 20-minute lunch break in between. You are uninterrupted here, with no engineers or HR to talk to; just enjoy your meal.
